I am in the middle( 9am 10/18/03) of installing rebuilt 1015c on my 1987 300sdl. Three things are different from stock compressor- no bushing reliefs in mounting locations, switch on back of compressor not installed, pully diameter slightly smaller-~ 1/2 inch dia.. What does the switch do and can the old one be transferred to new comp? Seems to be epoxied on. Is the slightly smaller pully the current standard? It is NOT the size of a 10p17c ie much smaller. I am worried the belt will not tighten up ---run out of adjustment. Thanks for all replies

If everything else is ok it might be easier to just buy a shorter belt...
That may be what is called a ' superheat' switch..
